### 3/5 — 模型更新

*2024-04-13*

什么时候能更新一下模型啊
大半年了都

### 4/5 — Update

*2023-12-07*

I originally gave this 5 stars but there needs to be a downscale option so that you can limit the upscale

**Developer response:** We did attempt to incorporate a pre-downscale feature during the development stage. However, despite subsequent upscaling, the image quality deteriorated significantly.

### 1/5 — Not even working anymore.

*2023-10-09*

It use to run a photos though my heritage and now it’s just broken.

### 4/5 — Question

*2023-09-08*

if i buy the pro version will i be able to save the output image that is higher than 1280 pixels?

### 5/5 — Images!

*2023-09-04*

Best!!!

### 5/5 — Great results

*2023-08-27*

The app is really great and it gives great results. Hope to see the app growing. Thanks.

**Developer response:** Sorry, this is a bug, please update to the latest version.

### 4/5 — Some modes aren’t accessible

*2023-08-21*

The Photo and Anime Illustration modes in the  Real-ESRGAN algorithm aren’t accessible, I can’t select neither one of them.

**Developer response:** Sorry, this is a bug, please update to the latest version.

### 1/5 — 👎

*2023-05-14*

There is a watermark even after activating the program

**Developer response:** The watermark is only used to identify the original image and the processed image for easy comparison.
There is no need to screenshot to export images.
You can click the button in the upper right corner and use the save or share function provided by the app to export images without watermark, and the images exported by the free version also have no watermark.

### 1/5 — 选择目录后程序崩溃，垃圾产品

*2023-04-07*

太垃圾了

### 4/5 — Great model selection, just needs video support

*2023-03-24*

There isn’t much of a selection yet on mobile devices for AI upscaling or interpolation models, just Waifu2x and a couple other random little apps. I think the capabilities and speed of these models will make them commonplace one day, so I’m excited to see a developer working on implementing Rife and other models into their app.
I know it’s not an easy ask, but Rife 4.6 for video files would be AMAZING. It’s the best interpolation model I’ve used, and FlowFrames (windows app) gives almost real-time speed with the VapourSynth implementation. Exciting stuff! Hope to see this app continue to grow and evolve.
